Culture-Centered OD era
Kurt Lewin's action research and force-field analysis framed organizational change as a social process requiring participatory diagnosis and iterative feedback. Richard Beckhard crystallized culture-centered OD with survey feedback, team-building, and planned change, linking diagnostic findings to readiness and commitment. Morton Deutsch's intergroup conflict work offered structured interventions to reduce tensions between groups and translate culture into cooperative practice within organizations. Edgar H. Schein advanced the culture-centered view by describing organizational culture as artifacts, values, and basic assumptions that can be shaped through socialization and learning-oriented change.
